The final battle of Brother Uchiha, it's the most tragedy..I try to recall and give a best answer to myself, why this happened, but nothing can do. (355-359) When Sasuke called the fire ball to struggle, the only thing he saw was revenage, the only thing in mind was send his dear brother to grave.I turst that Itachi was cried many times when he's alone.We all know his young brother was his live, but that's why the tragedy happened.
